1.20 ++ * Core file format: The core file is written in such a way that gdb
1.21 ++ * can understand it and provide useful information to the user (under
1.22 ++ * linux we use the `trad-core' bfd). The file contents are as follows:
1.23 ++ *
1.24 ++ * upage: 1 page consisting of a user struct that tells gdb
1.25 ++ * what is present in the file. Directly after this is a
1.26 ++ * copy of the task_struct, which is currently not used by gdb,
1.27 ++ * but it may come in handy at some point. All of the registers
1.28 ++ * are stored as part of the upage. The upage should always be
1.29 ++ * only one page long.
1.30 ++ * data: The data segment follows next. We use current->end_text to
1.31 ++ * current->brk to pick up all of the user variables, plus any memory
1.32 ++ * that may have been sbrk'ed. No attempt is made to determine if a
1.33 ++ * page is demand-zero or if a page is totally unused, we just cover
1.34 ++ * the entire range. All of the addresses are rounded in such a way
1.35 ++ * that an integral number of pages is written.
1.36 ++ * stack: We need the stack information in order to get a meaningful
1.37 ++ * backtrace. We need to write the data from usp to
1.38 ++ * current->start_stack, so we round each of these in order to be able
1.39 ++ * to write an integer number of pages.
